PICL Plug-In Library Functionsptree_walk_tree_by_class(3PICLTREE)


NAME

 ptree_walk_tree_by_class - walk subtree by class

SYNOPSIS

 
cc [flag ...] file ... -lpicltree [library ...] 
#include <picltree.h>
int ptree_walk_tree_by_class(picl_nodehdl_t rooth, const char *classname, void *c_args, int (*callback)(picl_nodehdl_t nodeh, void *c_args));

DESCRIPTION

 

The ptree_walk_tree_by_class() function visits all the nodes of the subtree under the node specified by rooth. The PICL class name of the visited node is compared with the class name specified by classname. If the class names match, the callback function specified by callback is called with the matching node handle and the argument provided in c_args. If the class name specified in classname is NULL, then the callback function is invoked for all the nodes.

The return value from the callback function is used to determine whether to continue or terminate the tree walk. The callback function returns PICL_WALK_CONTINUE or PICL_WALK_TERMINATE to continue or terminate the tree walk.

RETURN VALUES

 

Upon successful completion, 0 is returned. On failure, a non-negative integer is returned to indicate an error.

ERRORS

 
PICL_NOTNODE
Not a node
PICL_INVALIDHANDLE
Invalid handle specified
PICL_STALEHANDLE
Stale handle specified
PICL_FAILURE
